What types of pipes cannot have pipe vision mirrors installed?
Thread Content
As the title suggests, what types of pipes cannot have pipe sight glasses installed? Are there some pipelines carrying highly toxic or explosive substances for which sight glasses cannot be installed? Under what conditions is it necessary to add energy? Are there any relevant specifications available? I hope fellow sailors can offer some advice!

A pipe sight glass is one of the main accessories in industrial piping systems; it allows for continuous monitoring of the flow of liquids, gases, steam, and other substances within the pipes, enabling oversight of production processes and helping to prevent accidents during manufacturing. It is commonly used in production pipelines in industries such as petroleum, chemicals, textiles, and pharmaceuticals. Pipe sight glasses are designed and manufactured with reference to materials such as the \"Chemical Process Piping Manual\" and HG501-502-86 \"Sight Glasses for Piping and Pressure Vessels\", and can also be designed and manufactured according to specific requirements. The takeover flange is generally manufactured in accordance with the HG0594-97 standard. Shell material, window material, operating temperature, nominal pressure, seal material, connection type, allowable rapid temperature change, operating pressure, flange standard: carbon steel, stainless steel, steel lined with fluorine; borosilicate glass, quartz glass. Operating temperatures range from 0°C to 180°C or from 0°C to 300°C. Nominal pressures are <0.6 Mpa or 0.6 Mpa to 1.6 Mpa. Seal materials include nitrile rubber and polytetrafluoroethylene. Connection methods are threaded connection and flange connection. Allowable rapid temperature change is <60°C. Nominal pressures range from 0.6 Mpa to 2.5 Mpa. Flange standard: HG0594-97 (designation can also be based on specific requirements). Manufacturing and testing standards: Design, manufacturing, and inspection shall be carried out in accordance with the “Chemical Pipeline Manual” and HGJ501-502-86 “Pressure Window Viewports”.
Reply to 2# wanfaan221: I can’t agree. At least I know that acrylonitrile pipelines (which are highly toxic) cannot be used; if the sight glass breaks, a leak will occur, posing a safety risk.
Be vigilant for leaks in toxic pipelines; use sight glasses to identify leak points. Sight glasses are necessary for adding liquid materials and to monitor layering
Liquids containing tar should not be contained in containers
